Decode a Model Number

Decoder logic compiled from manufacturer nomenclature guides — Carrier (WeatherMaker / WeatherMaster / WeatherExpert, 48TJ/TF/TM & 48/50HJ legacy, 58-series furnaces), York / JCI (Sunline, Predator, Sun Choice / Sun Core / Sun Pro, Quantech chillers), Trane (Precedent / Voyager / IntelliPak / Foundation), Lennox / Allied, Rheem, Goodman, AAON, McQuay/Daikin, ICP (Heil / Tempstar / Day & Night), Nordyne, and BDP-era Bryant / Day & Night / Payne. Results are a best-effort reading of the model code — always confirm critical specs (tonnage, voltage, heat input, refrigerant) against the unit rating plate or manufacturer literature before ordering or quoting. Each result cites the factory document it was decoded from.
